Application fue@ ray 14, 1901. 'serial No'. 60,207. (No man.)

To @ZZ whom it may concern:

Beit known that I, HENRY W.WALDMIRE, a

citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a certain new and useful Improvement inVentilators, of which the following is a specification. My invention relates to Ya new andV useful improvement in ventilators, and has for its object to provide a ventilator which will be ofa cupola form and arranged above the room or apartment to be ventilated and be v provided with valves, which valves can be operated entirely from a central rod.

Another object of my invention is to provide hoods `or protectors which surround'theA ventilator in dilferent parts to allow the valves to be open and yet prevent the rain or snow from beating in.

With these ends in view this invention consists in the details of construction and combination of elements hereinafter set forth and then specically designated by the claims.

In order that those skilled. in the artto' which this invention` appertains may under.- stand how to make andl use the same, the construction and operation will now be `described in detail, referring to the a'ccoinpa` nying drawings, forming a part of this speciication, in which-- Figure 1 represents a lvertical section through my ventilator; and Fig. 'Zisa verti: cal section taken at right angles. to Fig.v l.

In carrying out my invention as here embodied, A represents a base whichisada'ptedl to fit kover an opening communicating with the apart'ment'to be ventilated. iv Thisbase A l is preferably made square, as is'the wellknown ventilator. The walls of the base A slant inward, as indicated atiB,.and form a square portionwhich is smaller thanvthe base A. 'Through each of the yfour walls of thisA portion are formed openings, which openings are adapted to be closed by pivoted valves C. The openings whichl the valvesare adapted to close have flanges formed at'each side, andy the valves vC'have also lianges upon their sides, and through both these vflanges pass the pivots D. Afiange E is formed upon the outside of the framework of the ventilator.

, The lower portion of the Valves Care formed so that when the valves are closed over the openings these ilanges E will pass'into. cavities formed by. bending the valve which will prevent the rain from entering the interior of the ventilator whenthe valves areclosed.

\ the valves when they are closed.

i Fis a vertical rod which extends up through the center of the ventilator and is guided in suitable guideways, as represented at G and H. This vertical rod F has secured to it the collar I, which has pivoted to it fourl rods J, which extend out in four dierent directions and are pivoted at their other ends to the `valves C. Thus when the rod F is pushed upwardthe valves CV will be rocked outward degre'ethat the valves are opened depends upon rthedistanoe the rod F is pushed upward. fA'friction-spring K, secured `to the `cross-piece G and bearing against the rod, l serves to hold the rod F in any desired posi-V tion. -l

. vAbove that l portion of the ventilatorvin Whichthe valves C are pivoted the framework projects out horizontally, and from the in twovfaces -of this slanting portion are pivoted large valvesL, which are pivoted to they wallsof the ventilator atj'the point l; When thesevalves L? are closed,ftheir` lower, edges restfwithinthegrooveMat 4the edge of the `projectinglhoriz`ontal portion of the framework for the purposeof :preventing rain -or sn ow;from lbeating in. v These valvesL are fupon thefpivots, so as to open the same. The

,o'uteredgeofthisprojecting portion it extends upward"inotheformiof .a pyramid, andopened and closed similarto the 'valve C by 4 means of rods or' llinks N,one endA of which 'isfpivotedto two of the links orrodsal and. the otherends are pivoted to 'the valves L.'

Thus when the rod F is raisedv or lowered both the valves C and valves L will be opened or closed. The other two sides of the inclined portion corresponding with that portion in which the valves L are located have openings `in which glass Qis insertedvfor the purpose oliadmitting light. The upper part of the structure has an opening O, which-opens up IOO ward and is adapted to be normally closed by a cap or valve P, which is secured also to the rod F, and when this rod is pulled to its lowest position the cap or valve P will close the opening; but when the rod F is pushed upward the cap will be raised from olf the opening and allow ventilation through this portion of the structure also.

Vhile I have described two of the sides of the pyramidical portion having valves located therein and the other two sides being glazed, it is obvious that valves could be formed in all four sides,or that all four sides could be glazed.

The latter construction would probably be preferable, as the lower ventilator C and the central upper ventilator P will allow sufficient ventilation for all practical purposes, and the four sides being glazed will admit a quantity of light while at the same time affording Ventilation.

As far as I have described constitutes the ventilator proper and could be used as a ventilator without any further apparatus Whatsoever; but in some cases when it would be desirable to open the valves even while it was raining or storming in any other manner I provide shields or hoods which will allow ventilation while at the same time preventing rain or snow from entering through the open valves.

R is a square shield which passes entirely around the outside of the ventilator around that portion in which the valves C are located and is upheld and supported bystrips S, which connect the same with the framework of the ventilator. Around the upper portion of the ventilator passes another square shield T, which is upheld and secured to the framework of the Ventilator by the strips U. This shield T is open at the top, but suspended within this shield and located directly above the opening O and valve P is a pyramidicalshaped hood V, which is supported by the cross-pieces W, which are secured to the shield T. These hoods or shields do not necessarily have to be used in connection with -my particular form of ventilator, but could with a slight Variation in the design be used in other forms of ventilators.

The principal advantage of my invention is thatby glazing the sides of the pyramidical portion the room to be ventilated is well lighted at all times through the ventilator either when the valves of the ventilator are open or closed.

Another advantage of my invention is that while being comparatively easy and cheap to manufacture it affords the best possible protection against the weather when the valves are closed, and all the valves are easily opened or closed by one operation, and these valves can be opened or closed to any desired degree.

`Of course I do not wish to be limited to the exact construction here shown, as slight modiications could be made without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new and useful isl. In a ventilator,the lower portion of which is composed of vertical walls, openings formed through these vertical walls,valves pivoted in said walls and adapted to open or close said openings, the upper portion of said ventilator formed of pyramidical shape, openings formed through two faces of this pyramidical portion, valves pivoted to the framework and adapted to open or close these openings, a central'rod passing upward through suitable guideways in the Ventilator, connections between all of the valves and this central rod so th at when said rod is pushed upward the valves will be opened, openings formed through the close the opening, a flange extending outward from the vertical walls below the openings, a recess formed in the lower edge ot' these valves and adapted to embrace said fiange when the valves are closed, a central rod extending up through the center of the Ventilator, suitable guideways for guiding this rod, a collar secured to the rod, four links, one end of each of which is pivoted to said collar, the other end of each of said links being pivoted to each of the four valves, the upper part of the framework of the ventilator being of pyramidical formation, openings formed through two faces of this pyramidical portion, valves pivoted to the frame` work and adapted to open or close said openings, grooves formed in the framework ofthe ventilator into which the ends of the valves are adapted to rest when said valves are closed, two links, one end of each being pivoted to each of the last-named valves, the other end of the links each pivoted to one of the links connecting the collar with the lower valves, openings formed through the remaining faces of the pyramidical portions, glass adapted to be inserted in said openings, an opening formed through the top of the ventilator, a Valve secured to the central rod and adapted to open and close lsaid opening, means for holding the central rod in any position it is placed, substantially as described and for the purpose specified.

3. In a ventilator', a rectangularstructure, the lower portion of which is composed of vertical walls, openings formed through each of the four vertical walls, valves pivoted in these vertical walls and adapted to open and close the opening, an openin g formed through the upper part of the ventilator adapted to open upward, a central rod, a valve secured upon the upper end of said central rod and Ido adapted to open or close the upperopening, means whereby the other valves of the ventilator are opened and closed by the movement of the central rod, a shield adapted to surround the lower portion of the ventilator in which the lower valves are placed, a shield adapted to surround the upper portion of the ventilator so as to protect the upper opening horizontally, a hood arranged above the upro per opening and adapted to protect said opening vertically, substantially as described and for the purpose speoied. v
